BUILDING-TALL CONSTRUCTION.

Application filed February 8, 1922.

T 0 (IU- wizom it may concern Be it known that I, llnxnsr A. Rasmussen,citizen of the United States, residing at Oakland, in the county ofAlameda and State of California, have invented certain new and usefulImprovements in Buildinglfall Constructions, of which the following is aspecification.

My invention is a building wall construe-s tion which may be cheaplymanufactured and cheaply and rapidly erected, and when erected issubstantial and durable.

Referring to the annexed drawing in which my invention is illustratedand which forms a part of this specification:

Figure l is a plan view of a fragment of my wall structure. 7

Figure 2 is a vertical section of aportiou of my wall structure taken online 2-2 of Figure 1.

Figure 3 is a perspective of one of the wall slabs.

Figure 4 is a side View of one of the wall keys.

My wallstructurc includes an outer wall unit 1 and an inner wall unit 2spaced a short distance within. said outer unit. T he wall units areeach composed of a plurality of slabs 3 preferably rectangular in shape,laid end to end horizontally and superim posed side-edgewise instaggered relation like bricks in a brick wall. slabs are formed withdouble rabbets i and 5 respectively, the rabbets l being undercut towardthe inner side of the slabs and the rabbets' 5 being undercut toward theoutside of theslabs so that the slabs maybe laid end to end with therabbets 4i andfi 0t adj a cent slabs interengaging each other. llhelower and upper longitudinal edges of the slabs are formed with doublerabbets 6 and 7 respectively, the rabbets 6 being undercut toward theoutside of the slabs and the rabbets 7 being undercut toward the insideof the slabs so that the slabs may be superimposed upon each other withthe rabbets 6 and 7 of the immediately superimposed slabs interengagingeach other. The inter-engaging ends of the slabs of each horizontal rowstaggered with relation to the interengaging ends of the slabsimmediately above and be-- low. On the inside of each slab are recesses8 and 9 and 10, the recesses 8 and 9 being square and extending from theupper corners of the slab, and the recess 10 being rectangular andextending from the upper edge of The ends of the Serial No. 535,051.

the slab to a vertical depth less than that of the recesses 8 and 9.When erected the recesses 8 and 9 of adjacent slabs register with eachother and form single recesses which rest directly over the recesses 10in the slabs immediately below, and the recesses 8 and 9 and 10 of theslabs of the outer wall unit lie opposite corresponding recesses in theinner wall unit. The lower edges 11 of the recesses 8 and flare undercutor dovetailed while the side-edges of said recesses are beveledoutwardly. Plates 12 are placed between the outer and inner wall units 1and 2, and rest upon the lower edges of opposite recesses 10 in saidwall units. Keys 13 consist ofrectangular plates formed with undercutshoulders 1 at their side edges near the tops thereof. These keys areplaced in pairs betweenthe outer wall unit and the inner wall unit, withthe keys of each pair spaced a short distance apart, so that each pairrests upon a plate 12 and the shoulders 1.4 of the keys of the pair restrespectively on the lower edges 11 ot the opposite recesses 8 and 9 inthe outer and inner wall units directly above the plate, one keyengaging the side edge of the recess 8, and the other key engaging theside edge of the recess 9, and the upper edges of the keys coincidingwith the upper edges 01" said recesses. Cement or concrete is pouredbetween the keys of each pair upon the plates 12 and when hard binds thewallsltogether at their joints, and effectively seals the verticaljoints between the slabs. I The corner slabs 15 and 160i the inner andouter wall units maybe formed with slab members 17 and 18 extending atright angles to each other. These slabs are otherwise the same as theslabs 8. y j l v Having described my nvention, I claim:

1. A wall construction including an in nei' unit, an outer unit, eachunit comprising slabs laid end to end in horizontal rows superimposedupon each other, the end joints of each row-being staggered withrelation to the end joints of adjacent rows, the ends of the slabs beingrabbeted to interengage each other, the lower and upper edgesv of theslabs being rabbeted to interengage each other. recesses formed on theinside of the slabs at the upper corners thereof so that the cornerrecess of each slab registers with the corner recess of the adjacentslab, the lower edgesof said corner recesses being undercut, the slabsbeing also formed on their inside at their upper edges with platesupporting recesses directly below the registering corner recesses,plates placed between the outer and inner Wall units upon the loweredges of opposite plate support ing recesses, keys "formed with undercutshoulders arranged in pairs spaced a short distance apart and placed sothat each pair rests upon a plate and the undercut shoulders thereofengage the undercut lower edges or the corner recesses above said plate,and a cement filling between each pair of keys.
